DETAILED DESCRIPTION

FIGS. 1-13 illustrate example carwash methods that enable a customer 10 to purchase one or more carwash options online and then use a smartphone with an app to actually start the car washing process. The intention is to encourage patron loyalty to carwash chains or franchises that employ the convenient method.

An example of the method might proceed as follows. A customer 10 uses a home computer or smartphone (FIG. 1) to access a carwash franchise website 14. By way of the website, customer 10 enters a user name, e.g., DRIVER, and makes an online payment for three carwashes, e.g., two standard washes and one deluxe wash. At some later period while traveling in a vehicle 12, customer 10 uses his smartphone to find the nearest participating carwash. Customer 10 then drives vehicle 12 to the carwash. Upon arriving at the carwash, customer 10 decides to wait in line for carwash bay-A (FIG. 2). Customer 10 then uses his smartphone to announce he's at the carwash and that he wants the deluxe wash (FIG. 2). In some examples, customer 10 might use icons 16 on the smartphone to inform the carwash that in this instance he would like the deluxe wash. A carwash controller 20 and/or vendor computer system 22 identifies the customer upon recognizing his password, DRIVER. Based on a GPS reading from the smartphone, carwash controller 20 and/or vendor computer system 22 determines whether vehicle 12 is at the entrance of carwash bay-A (FIG. 3). Otherwise, in some examples, customer 10 might use icons 24 on his smartphone (FIG. 1) to tell the carwash he's in the line leading to bay-A. If vehicle 12 is at the entrance of carwash bay-A, and bay-A is available to receive vehicle 12 (FIG. 3), then carwash controller 20 and/or vendor computer system 22 invites customer 10 to enter the carwash bay. Customer 10 drives in and the car washing is performed (FIG. 4).

In addition and/or as alternatives to using GPS, FIGS. 5-8 show other means for determining whether vehicle 12 is at the entrance of carwash bay-A or within 1.5 car lengths of the entrance (e.g., within about twenty feet). FIG. 5 shows customer 10 manually entering 26 a some sort of input (e.g., pressing a pushbutton) to carwash controller 20, FIG. 6 shows carwash controller 20 scanning 26 b a QR code 28 (Quick Response Code, which is a registered trademark of Denso Wave, Inc.) displayed on the customer's smartphone, FIG. 7 shows a limited distance wireless communication link 26 c (Bluetooth, WiFi, etc.) being established between carwash controller 20 and the customer's smartphone, and FIG. 8 shows carwash controller 20 locally displaying 26 d a code that customer 10 first reads and then confirms/repeats by entering the code into his smartphone or inputs into carwash controller 20. Reference numbers 26 a, 26 b, 26 c and 26 d each are examples of a local communication link 26.

In some example carwash methods, the method involves the use of one or more of the following: vehicle 12, a carwash 30 with a first carwash bay 30 a and sometimes a second carwash bay 30 b, carwash controller 20, vendor computer system 22, and a customer digital system 32.

In some examples, portable digital device 36 in the form of a cell phone, smartphone or touchpad tablet, includes an integral GPS receiver in communication with a satellite system 38 for acquiring one or more GPS coordinates 40 or location signals that identify the location of portable digital device 36. In some examples, portable digital device 36 has Internet access or communication via an Android operating system, wherein ANDROID is a registered trademark of Google Inc., of Mountain View, Calif. IPAD is a registered trademark of Apple Inc., of Cupertino, Calif.

One example carwash method is illustrated in FIG. 9, wherein block 42 represents customer 10 submitting a request for one or more carwash operations (e.g., low cost standard wash, premium wash, deluxe wash, etc.) at carwash 30. The request can be submitted in various ways including, but not limited to, customer 10 using customer digital system 32 (e.g., a desktop computer, smartphone, etc.) in communicating over the Internet via a wireless remote communication link 44 and/or 46 with carwash website 14 posted by vendor computer system 22. For example, block 48 represents customer 10 requesting a carwash operation by entering an input (e.g., mouse-clicking on low cost standard wash icon 16 a, premium wash icon 16 b, deluxe wash icon 16 c, etc.) to portable digital device 36, wherein customer 10 can carry portable digital device 36 in vehicle 12.

Still referring to the example of FIG. 9, block 50 represents customer 10 or website 14 assigning an identity 52 (user name, password, etc.) to portable digital device 36, and conveying/communicating identity 52 to website 14. Block 54 represents customer 10 using customer digital system 36 for making an online Internet payment (credit card, PayPal, etc.) that covers the cost of the one or more requested carwash operations. Block 56 represents website 14 associating identity 52 to the online Internet payment so that at least one of vendor computer system 22 and carwash controller 20 knows that the customer with portable digital device 36 has paid for a carwash operation. Vendor computer system 22 and/or carwash controller 20 later uses this information in confirming the identity of portable digital device 36 at the carwash, as illustrated by block 58.

Still referring to FIG. 9, upon approaching carwash 30 or at some point prior to entering carwash 30, customer 10 selects a desired carwash bay (e.g., bay 30 a or 30 b) if carwash 30 has more than one carwash bay. Customer 10, for example, might select whichever carwash bay has the shortest line of cars. Block 60 represents customer 10 selecting via portable digital device 36 carwash bay 30 a or 30 b from a plurality of carwash bays, thereby telling carwash controller 20 which bay vehicle 12 intends to enter. In some examples, customer 10 selects bay 30 a or 30 b and informs carwash controller 20 of the choice by clicking on one of a plurality of icons 24.

Still referring to FIG. 9, block 62 represents vendor computer system 22 and/or carwash controller 20 determining whether the chosen carwash bay 30 a is available to receive a vehicle for the carwash operation. Block 62 also represents vendor computer system 22 and/or carwash controller 20 determining whether portable digital device 36 in vehicle 12 is within a predetermined distance 64 (FIG. 3) of the entrance of carwash 30. In some examples, predetermined distance 64 is about 1.5 car lengths or about twenty feet. In some examples, determining whether portable digital device 36 is within distance 64 is achieved by vendor computer system 22 and/or carwash controller 20 considering the GPS coordinates 40 of portable digital device 36, as illustrated by block 70. If portable digital device 36 is within distance 64 and the carwash is available for the carwash operation, then vendor computer system 22 and/or carwash controller 20 allows the carwash operation request, and carwash 30 performs the chosen carwash operation on vehicle 12, as illustrated by block 66. If, however, portable digital device 36 is beyond distance 64, vendor computer system 22 and/or carwash controller 20 disallows the carwash request and inhibits the carwash operation, as illustrated by block 68.
